Shipping Order Allocation Apparatus

1. A shipping order allocation apparatus comprising a processor and a storage device and configured to allocate shipping orders to shipping order groups, wherein the storage device holds: shipping order information indicating shipping orders and articles included in the shipping orders; shipping time-limit information indicating shipping time limits of the shipping orders; and article location information indicating blocks where articles included in the shipping orders are stored, and wherein the processor is configured to: create a shipping order group composed of shipping orders included in the shipping order information; acquire a time to start picking for the shipping order group; acquire blocks where articles included in the shipping order group are stored from the article location information and calculate a total worktime for the picking of the shipping order group based on the acquired blocks; determine whether the picking work for the shipping order group is completed by the earliest shipping time limit among shipping time limits of the shipping orders in the shipping order group based on the shipping time-limit information, the time to start the picking, and the total worktime for the picking; calculate an evaluation value of the shipping order group for which the picking work is determined to be completed by the earliest shipping time limit among the shipping time limits of the shipping orders in the shipping order group, based on the blocks storing the articles included in the shipping order group; and determine whether to include the shipping order group in a result of allocation to shipping order groups, based on the evaluation value.

2. The shipping order allocation apparatus according to claim 1 , wherein the storage device further holds: block-to-block distance information including information on distances between a picking start point and an article storage blocks, a distances between article storage blocks, and distances between a picking end point and article storage blocks; and parameter information including a traveling speed and a picking time per piece of an article, wherein the shipping order information includes information indicating quantities of the articles included in the shipping orders, and wherein the processor is configured to: calculate a total travel distance to pick all articles included in the shipping order group based on the shipping order information, the article location information, and the block-to-block distance information; and calculate a total worktime for entire picking work inclusive of traveling in picking the shipping order group based on the total travel distance, the traveling speed, the quantities of the articles included in the shipping orders in the shipping order group acquired from the shipping order information, and the picking time per piece of an article.

3. The shipping order allocation apparatus according to claim 1 , wherein the storage device further holds information on distances between article storage blocks including information on distances between a picking start point and article storage blocks, distances between article storage blocks, and distances between a picking end point and the article storage blocks, and wherein the processor is configured to: calculate a total travel distance to pick all articles included in the shipping order group based on the shipping order information, the article location information, and the information on distances between article storage blocks; and calculate the evaluation value based on the total travel distance.

4. A method for allocating shipping orders to shipping order groups by a shipping order allocation apparatus, wherein the shipping order allocation apparatus holds: shipping order information indicating shipping orders and articles included in the shipping orders; shipping time-limit information indicating shipping time limits of the shipping orders; and article location information indicating blocks where articles included in the shipping orders are stored, and wherein the method comprising: creating, by the shipping order allocation apparatus, a shipping order group composed of shipping orders included in the shipping order information; acquiring, by the shipping order allocation apparatus, a time to start picking for the shipping order group; acquiring, by the shipping order allocation apparatus, blocks where articles included in the shipping order group are stored from the article location information and calculating, by the shipping order allocation apparatus, a total worktime for the picking of the shipping order group based on the acquired blocks; determining, by the shipping order allocation apparatus, whether the picking work for the shipping order group is completed by the earliest shipping time limit among shipping time limits of the shipping orders in the shipping order group based on the shipping time-limit information, the time to start the picking, and the total worktime for the picking; calculating, by the shipping order allocation apparatus, an evaluation value of the shipping order group for which the picking work is determined to be completed by the earliest shipping time limit among the shipping time limits of the shipping orders in the shipping order group, based on the blocks storing the articles included in the shipping order group; and determining, by the shipping order allocation apparatus, whether to include the shipping order group in a result of allocation to shipping order groups, based on the evaluation value.

5. The method according to claim 4 , wherein the shipping order allocation apparatus further holds: block-to-block distance information including information on distances between a picking start point and an article storage blocks, a distances between article storage blocks, and distances between a picking end point and article storage blocks; and parameter information including a traveling speed and a picking time per piece of an article, wherein the shipping order information includes information indicating quantities of the articles included in the shipping orders, and wherein the method further comprising: calculating, by the shipping order allocation apparatus, a total travel distance to pick all articles included in the shipping order group based on the shipping order information, the article location information, and the block-to-block distance information; and calculating, by the shipping order allocation apparatus, a total worktime for entire picking work inclusive of traveling in picking the shipping order group based on the total travel distance, the traveling speed, the quantities of the articles included in the shipping orders in the shipping order group acquired from the shipping order information, and the picking time per piece of an article.

6. The method according to claim 4 , wherein the shipping order allocation apparatus further holds information on distances between article storage blocks including information on distances between a picking start point and article storage blocks, distances between article storage blocks, and distances between a picking end point and the article storage blocks, and wherein the method further comprising: calculating, by the shipping order allocation apparatus, a total travel distance to pick all articles included in the shipping order group based on the shipping order information, the article location information, and the information on distances between article storage blocks; and calculating, by the shipping order allocation apparatus, the evaluation value based on the total travel distance.
